摘要

Method for reconstructing seismic data. The method includes receiving at a computing device an input seismic data set d related to plural shots emitted by one or more seismic sources; receiving at the computing device a positional data set dp relating to recording locations of the receivers that recorded the input seismic data set d; receiving at the computing device a receiver target location; calculating an adjusted receiver location based on (i) the positional data set dp and (ii) the receiver target location, wherein the adjusted receiver location substantially coincides with a receiver location from the positional data set dp; calculating reconstructed seismic data dr at the adjusted receiver location using the input seismic data set d and the positional data set dp; and correcting the seismic wave paths from the one or more seismic sources to the receivers based on the reconstructed seismic data dr.
